■ Put a layer of litter in a tray, or use sand if your cat will eventually use outdoor facilities. For two cats, provide at least two trays.
■ Place the tray in a quiet corner, away from food and water bowls.
■ If the kitten messes on the floor, transfer the puddle or solid matter to the tray. Don’t be cross, but do it with a firm “This is where you do it.”
■ Clean the tray twice a day, using only hot water and detergent.
■ If your cat has an accident, wash the area with a 10 per cent solution of biological washing powder, spray with vinegar and scrub again.
